Here’s an interesting analysis from the New Oxford review. The number of “Catholics” in the U.S. continues to climb but Mass attendance, numbers joining religious orders, etc. is declining.
“The U.S. Catholic Church statistics presented in this book are truly ominous. Virtually every indicator of Church well-being (priests, ordinations, seminarians, religious orders, high schools, grade schools, sacramental life, Mass attendance, etc.) is in precipitous decline. And of those calling themselves Catholics, fewer and fewer follow Church rules or accept Church doctrine. Yet the total number of Catholics in the U.S. continues to rise! Since the mid-1960s, when all these indicators went into freefall, Church membership has actually risen by 43 percent, and continues to rise at a rate of more than 700,000 Catholics each year. With the Church in collapse by almost every measurable standard, her membership continues to increase!”
